Richard K. Campbell, 58, was a security guard at the Hilton Netherland Plaza Hotel, located at 35 West Fifth Street.

Police say Campbell was a Vietnam Veteran who was killed on his birthday.

Campbell was considered a mentor in his Westwood community.

"He said don't be in the streets or nothing, he said just stay good," said Jeffrey Steele, an 18-year-old who lived below Campbell.

Steele says Campbell took him to vote for the first time.

"He said I'm going to take you, it was his day off, he said I'm going to take you to go vote," said Steele.

Campbell was found at about 6 a.m. Friday. The case is being investigated as a homicide after Campbell was found with apparent stab wounds, according to police.

Police say Campbell was scheduled to be off Friday and was not working his regular shift.

A hotel employee called 911 saying they had found the security guard dead inside the hotel.

"This morning a member of our security staff was involved in a situation with an unknown person in an emergency staircase in the Carew Tower Complex. The officer, an eight-year member of our team and loved staff member has died. Pending notification of relatives, his name is being withheld. Our most sincere condolences go to the officer's family. His friends and colleagues here at the hotel are deeply saddened by this senseless loss," Managing Director Michel Sheer said in a press release Friday,

Officials have not released any additional information at this time.
